摘要： A transistor drive circuit arrangement in which the collector current of a transistor is passed through the primary or control windings of a direct current current-transformer or transductor and the secondary or output windings of the current-transformer or transductor control the passage of alternating current via rectifying means which provides base current drive for the transistor. Thereby the base current is directly related to instantaneous collector current which results in significant power economies relative to prior art arrangements in which the base is continuously over-driven to ensure permanent base-emitter saturation.
